Telestones are medium-sized rectangular devices that allow the user to initiate communication with anyone in the world of Songhaven so long as they know their name. When calling another, if they possess a Telestone, the unit will display a hologram of the person being reached. If more than one person is being called, no holograms will show, and names of callers will instead be displayed. Telestones can call normal phones, though there will also be no holograms in these cases, and reception will be poorer.
Invented by Wish Works, more variations of Telestones are currently being worked on, with a version that can host text and a network of saved videos being pioneered.
